AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
336 AM EDT TUE APR 19 2011

.SHORT-TERM...TUESDAY THROUGH WEDNESDAY NIGHT

WEST TO EAST ORIENTED BAND OF RAIN ROUGHLY SANDWICHED BETWEEN THE
INTERSTATE 80 AND 70 CORRIDORS WILL CONTINUE TO LIFT SLOWLY NORTH
AND EAST THIS MORNING. THIS PRECIPITATION IS ASSOCIATED WITH A LEAD
SHORTWAVE IN FAST WESTERLY FLOW ALOFT. LIFT WITH THIS FEATURE
COMBINED WITH A LOW LVL BAROCLINIC ZONE ACROSS THE NRN OH VALLEY HAS
LED TO A RATHER DEEP AND VIGOROUS FRONTAL CIRCULATION OVER THE FA
THIS MORNING. THIS PRECIPITATION ALSO HAS SUPPORT FROM LINGERING
RIGHT ENTRANCE UPPER JET DYNAMICS ABOVE THE ABOVE MENTIONED
FRONTOGENETIC LAYER. EXPECT THE ORGANIZED SHOWER ACTIVITY TO TAPER
OFF BTW 12-15Z PER LATEST 3KM HRRR PROGS AS THE WEAK MID LEVEL
IMPULSE EXITS EWD.

THE FA WILL REMAIN NORTH OF THE SFC BOUNDARY TODAY...RESULTING IN A
RATHER RAW AND CLOUDY DAY GIVEN AN IMPRESSIVE LOW LEVEL INVERSION
OVER THE AREA. ALSO SHOULD SEE OUR SFC EASTERLY WINDS INCREASE
DURING THE DAY PER EXPECTED PRESSURE FALLS TO THE WEST. THE 850 HPA
FRONT WILL LINGER OVER AT LEAST THE NRN HALF OF THE FA...WITH
CONTINUED 40-50 KNOTS OF CROSS ISOBARIC ISENTROPIC FLOW NORTH OF THE
ABOVE MENTIONED SFC BOUNDARY THAT WILL REMAIN SITUATED NEAR THE
INTERSTATE 70 CORRIDOR. WITH THIS...EXPECT A FEW LINGERING SHOWERS
AND/OR DRIZZLE LATE THIS MORNING INTO THE AFTERNOON GIVEN THE
LINGERING ISENTROPIC ASCENT OVER THE MOIST INVERSION.

FOCUS THEN TURNS OUT WEST WHERE A PAIR OF WELL-DEFINED SHORTWAVES
RESIDE AS OF 07Z. THIS ENERGY WILL SPILL OUT INTO THE PLAINS THIS
MORNING...WITH THE COLORADO WAVE PROGGED TO PIVOT NEWD TOWARDS THE
WESTERN GREAT LAKES BY LATE THIS AFTERNOON INTO TONIGHT. HEIGHT
FALLS AND DPVA WILL AID IN CYCLOGENESIS ACROSS THE SRN
PLAINS...WITH THE MODEL CONSENSUS NOW AGREEING ON A SFC LOW TRACK
NEWD THROUGH NW INDIANA AND SW LOWER MICHIGAN TONIGHT. HIGH
MOMENTUM AIRSTREAM IN ADVANCE OF THIS TROUGH AND THE DEVELOPING
SFC CYCLONE WILL SUPPORT ROBUST 925-850 HPA THETA-E ADVECTION.
THIS SUPPORTS GOING CHC POPS SE TO LIKELY POPS NW THIS AFTERNOON
INTO THIS EVENING AS COLLOCATION OF INCREASING LARGE SCALE ASCENT
AND LINGERING 85-7H FGEN FORCING WILL BE MAXIMIZED OVER THE NW.
LARGE HAIL WILL BE THE PRIMARY THREAT WITH ANY CONVECTION DURING
THIS TIME GIVEN AMPLE INSTABILITY IN THE HAIL GROWTH ZONE.
STRONGLY FORCED SYSTEM WILL ROLE THROUGH TONIGHT...WITH SURFACE
BASED CONVECTION POSSIBLE ACROSS THE FAR SOUTH AND EAST. THIS IS
ALL DEPENDENT ON THE SFC LOW TRACK AND HOW FAR NORTH THE SFC
BOUNDARY MAKES IT. EXPECT SEVERE CONVECTION TO DEVELOP ACROSS
WEST-CENTRAL IL SWD INTO EASTERN MO LATE IN THE AFTERNOON...GROWING
UPSCALE AND ORGANIZING INTO A SQUALL LINE / LEWP AS IT TRACKS EWD
INTO THE OH VALLEY TONIGHT. THIS POTENTIAL SQUALL LINE WITH BOWING
SEGMENTS SHOULD HOLD TOGETHER AS IT TRACKS EAST GIVEN A STRONGLY
SHEARED ENVIRONMENT AND SUFFICIENT DOWNSTREAM INSTABILITY. THE
QUESTION REMAINS...HOW FAR NORTH CAN WE GET THIS BOUNDARY? AND AT
THIS TIME IT STILL LOOKS LIKE FAR SOUTHERN AND EASTERN AREAS
COULD BE UNDER THE GUN...WITH DAMAGING WINDS THE PRIMARY CONCERN.
ALTHOUGH ISO TORNADOES NOT OUT OF THE QUESTION ALONG THE SFC
BOUNDARY GIVEN SUCH HIGH VALUES OF 0-1 KM HELICITY/SHEAR. WILL
CONTINUE TO HIGHLIGHT THIS THREAT IN THE HWO AND ZFP/GRIDS.
ONLY CHANGE WAS TO RUN WITH A NON-DIURNAL TEMP CURVE TONIGHT...AND
ADD TEMPORAL DETAIL TO POPS/WX.

STRONG ISOLLABARIC COUPLET BEHIND THE COLD FRONT WILL PROVIDE FOR A
RATHER WINDY WEDNESDAY...ESPECIALLY DURING THE MORNING AND EARLY
AFTERNOON. CURRENTLY LOOKS LIKE WINDS SHOULD STAY JUST BLO ADVISORY
CRITERIA...ALTHOUGH QUICKER PHASING OF THE TWO ABOVE MENTIONED
SHORTWAVES OVER THE NRN GREAT LAKES WOULD RESULT IN A TIGHTER LOW
LEVEL HEIGHT GRADIENT AND ADVISORY LEVEL WINDS. OTHERWISE...EXPECT
BKN/OVC STRATO-CU OVER MAINLY OUR NRN AREAS ON WEDNESDAY GIVEN THE
EXPECTED CAA REGIME AND WRAP AROUND MOISTURE.

&&

.LONG TERM...
HIGH PRESSURE WILL MOVE ACROSS THE REGION THU PROVIDING THE CWA WITH
FAIR WX. AIRMASS WILL BE CHILLY THOUGH IN WAKE OF DEPARTING LOW
PRESSURE SYSTEM WITH HIGHS WELL BLO NORMAL IN THE L-M50S...EXCEPT
COOLER NEAR LM.

ANOTHER LOW PRESSURE SYSTEM WILL MOVE EAST ACROSS THE SRN PLAINS THU
NGT WITH WARM FRONT EXTENDING EASTWARD INTO THE OH VALLEY...POSSIBLY
RESULTING IN OVER-RUNNING PRECIP OVERSPREADING OUR CWA OVERNIGHT.
00Z GFS IS DEEPER WITH THIS SYSTEM THAN THE ECMWF AND WITH BETTER
RUN-RUN CONTINUITY AND MORE CONSISTENT HANDLING OF LOW MOVG ACROSS
THE AREA EARLIER IN THE WEEK... IS PREFERRED. THUS, THIS SYSTEM IS
EXPECTED TO TAKE A SIMILAR TRACK AS THE LOW TO MOVE THROUGH THE CWA
TUE NIGHT WITH SIMILAR IMPACTS... OVER-RUNNING SHOWERS AND SCT TSTMS
LIKELY WILL SPREAD INTO THE AREA FRI AS THE WARM FRONT APPROACHES.
TEMPS SHOULD RISE FRIDAY NIGHT ACROSS SE PORTION OF THE CWA AS THE
LOW TRACKS ACROSS THE NW. TSTMS MAY ACCOMPANY THE CDFNT AS IT MOVES
THROUGH THE AREA LATE FRIDAY NIGHT... THOUGH ONCE AGAIN GIVEN THE
TIME OF DAY FOR FROPA INSTABILITY SHOULD BE LIMITED... BUT GIVEN
STRONG WIND FIELDS/SHEAR ACCOMPANYING THE SYSTEM... THERE WILL BE
POTENTIAL FOR SEVERE STORMS IF INSTABILITY IS SUFFICIENT FOR DEEP
CONVECTION.

ANOTHER FAIRLY QUICK SHOT OF CAA EXPECTED BEHIND THIS SYSTEM ON SAT
WITH JUST A LOW CHC OF SOME LINGERING SHOWERS IN LOW LEVEL CYCLONIC
FLOW. FRONT AGAIN EXPECTED TO STALL ALONG THE OH VALLEY WITH ANOTHER
SHRTWV MOVG EAST ALONG THE BAROCLINIC ZONE SAT NGT BRINGING A BETTER
CHC OF RAIN TO THE CWA. NO CHANGE TO THE PATTERN INTO EARLY NEXT
WEEK WHICH APPEARS TO BE HANDLED WELL BY GOING FCST WITH A CHC OF
SHOWERS INTO MONDAY SO NO CHANGES MADE TO DAY6-7 GRIDS.

&&

.AVIATION.../06Z TAFS/

DETERIORATING FLIGHT CONDITIONS CAN BE EXPECTED AT EACH TERMINAL
THIS MORNING AS RAIN SETTLES IN AND MOISTURE LOCKS IN UNDER A
STRENGTHENING LOW LEVEL THERMAL INVERSION. THERE MAY BE A LULL IN
THE RAINFALL LATER THIS MORNING INTO THIS AFTERNOON AS A LEAD
SHORTWAVE TROUGH RESPONSIBLE FOR THIS PRECIPITATION PROPAGATES OFF
TO THE EAST. MORE ORGANIZED SHOWER AND THUNDERSTORM ACTIVITY WILL
LIKELY BUILD BACK INTO AT LEAST SBN BY LATER IN THE AFTERNOON AND
EVENING PER IMPRESSIVE LOW LEVEL THETA-E ADVECTION AHEAD OF AN
ADVANCING UPPER TROUGH. OTHERWISE...EXPECT GRADIENT WINDS TO
REMAIN OUT OF THE EAST FOR MUCH OF THE PERIOD AND INCREASE A BIT
TODAY GIVEN EXPECTED UPSTREAM PRESSURE FALLS.
